# The Problem with Onchain Yields
The onchain yield landscape today just isn’t cutting it. The problem isn’t a lack of options. Choose your adventure: onchain money markets, delta neutral strategies, staking protocols, or whatever yield farm is trending this week. The problem is that none of these options offer what yield should offer: stability, transparency, and sustainability.
DeFi users deserve more than reflexive rates, mystery meat emissions, and point-chasing games. Yields shouldn't rug. They should consistently reward.
At Mu Digital, we believe a superior yield primitive is overdue: one designed to deliver attractive, transparent and predictable returns from real economic activity. The evolution of real world assets will help guide a more sustainable DeFi future.
Onchain Yields are Volatile
In traditional finance, yield products promise a relatively stable investment return. Cash flow you can count on. Onchain? It’s a wild ride.
Most onchain yields today are reflexive. They don’t come from real economic activity, but from the performance of other crypto assets. The majority of “native yield” is funded by perpetual swap funding rates, which are themselves a byproduct of speculative demand.
In bull markets, perp traders pay high funding to stay long, and protocols pass that income along to users as “yield’. But when sentiment turns, funding dries up; and so does the yield.
It’s a circular system: crypto assets generate yield based on the trading activity of other crypto assets. There’s no diversification, no resilience and ultimately, no stability. As the broader crypto markets go – so do yield products fluctuate. In volatile markets, one might experience 30% yields yesterday that degrade to 3% tomorrow. In some cases yields have gone negative.
***That’s not yield folks – it’s leverage wearing a different jersey.***
Onchain Yields are Opaque
Try explaining where your DeFi yield comes from today. Without using the words “multiplier” or “points.”
Many onchain yield offerings suffer from a lack of transparency. Rather than deriving returns from identifiable, sustainable cash flows, they often rely on token emissions, liquidity incentives, or points programs that obscure the true source of yield.
At a fundamental level, any yield product should have clear transparency on what backs the promised returns. The base layer is the most important. Assets come in all flavors - with varying levels of risk / return characteristics. Not all risk is bad. In fact, risk is required to expect outsized returns. But any DeFi user should understand the underlying asset and associated risk they are taking.
***Transparent yield means knowing the underlying cash flows, not just chasing rewards.***
Onchain Yields Should be Guaranteed
DeFi has conditioned users to expect high, variable returns as the norm. That’s a dangerous precedent. In traditional finance, credit is synonymous with a more stable, predictable investment class.
Credit guru Howard Marks (Oaktree Capital) often highlights a fundamental advantage of credit lending: contractual certainty. Credit investments come with defined terms: interest payments, maturity dates, and legal recourse. These factors give investors a predictable path to returns.
Onchain yields, by contrast, rarely offer this kind of structure. They’re fluid, market-driven, and often governed more by tokenomics than enforceable obligations. But DeFi doesn’t have to reinvent the wheel. Yield should be grounded in contractual commitments - guaranteed payments tied to real-world performance, not abstract incentive loops.
***That’s how we move from speculation to reliability; how we build financial primitives that serious capital can trust.***
#### It’s Time to Reset the Yield Narrative
DeFi needs a new foundation. One that starts with credible, stable returns anchored in the real world.
At Mu Digital, we’re introducing a different primitive: connecting real-world corporate borrowers with onchain capital. That means:
* Real yield from real revenue-generating activity
* Transparent underwriting and borrower visibility
* A bridge between TradFi credit and DeFi efficiency
This is the path forward. Because yield shouldn’t just be another crypto game. It should be the backbone of capital formation onchain.
# The Case for Credit Assets
**Credit is boring. And that’s exactly why it’s attractive.**
Fixed income products, or credit markets, are the single largest global asset class, hovering between US$130-150 trillion (*source: Bank for International Settlements, McKinsey Global Institute, IFC / World Bank Group*). Credit instruments are financial contracts, such as bonds, loans, or notes, where one party lends money to another in exchange for a promise to repay with interest over time.
At their core, credit agreements signal the following pact: "Pay me what you owe me. Or else I take claim of your assets." No tokenomics wizardry. No "APYs" inflated by unsustainable trading fees. The investment is backed by a contractual agreement, real-world enforcement, and cold hard cash flow.
Credit investments offer:
1. ***Predictability***\
All types of credit investments - including bonds, loans and private credit - spell out when and how much you get paid. No praying for transaction volumes, no guessing which governance vote will slash your payout.
2. ***Risk-Adjusted Returns***\
Over decades, credit has delivered returns competitive with equities. Barclays data shows U.S. high-yield bonds returned \~7% annually from 1990–2020, with far fewer gut-wrenching drawdowns than the S\&P 500. The yields offered in faster growth regions such as APAC are much more attractive.
3. ***Seniority***\
When business performance goes sideways, creditors stand in front of the line. They have senior asset claims in the scenario of bankruptcy or asset liquidations. In DeFi, you're lucky if you even know where the exit is when the music stops.
#### Credit Assets vs. DeFi Yields: Know What You’re Betting On
DeFi yields can look sexy, until they aren't. When the cycle turns, vapor yields disappear faster than a rugpull.
Here's the real comparison:
| | ***Credit Assets*** | ***DeFi Yields*** |
| ------------------- | ----------------------------------------- | ------------------------------------------------------------------- |
| **Return Source** | Contractual debt payments | Trading fees, token inflation |
| **Risk Profile** | Credit risk, default cycles | Difficult to assess - Smart contract hacks, liquidity death spirals |
| **Transparency** | Audited financials, public ratings | Often opaque, DIY disclosures |
| **Liquidity** | Moderate (depends on market) | Nominally high, but can vaporize in stress events |
| **Track Record** | 100+ years of tested performance | 5–7 years of experimental volatility |
| **Yield Stability** | Tethered to contracts and real cash flows | Tethered to market mood swings and incentive programs |
DeFi yields are reflexive by design: they soar in bull markets when everyone’s greedy and collapse the second fear hits. They're built on flows, not fundamentals.
Credit, on the other hand, is built on legally binding promises to pay. Even when spreads widen and asset prices dip, your contractual cash flow keeps coming; unless there's an outright default (and even then, creditors get first crack at the leftovers).
### Changing the Paradigm
At Mu Digital, our focus is on asset selection. We bring over 30+ years of collective experience in origination of credit investments. Our mission is to source the most attractive yields across Asia Pacific and deliver these to the onchain economy.
# Asia is the New Alpha
The best investment opportunities from Asia don’t show up in your CEX, DEX or brokerage app. And you will want these returns.
You can earn up to 15% in Asia - more attractive than yields offered in developed economies such as the United States and European Union (EU). These returns are principal protected and backed by contractual obligations of the largest Asian governments and companies.
Why are you locked out?
* No access: Most Asian debt markets are only available to financial institutions and high net worth individuals
* No liquidity: Even if you could get in, you can’t get out. Secondary markets are typically settled over the counter (OTC) between banks
* Geographic gates: Asia is a vast region and investments are often locked within domestic borders. International access cannot be expected as the default

# How it Works
The Mu Digital protocol provides DeFi users with access to a diversified pool of USD-denominated, principal-protected real world assets (“RWAs”) through a dual token structure which allows users to choose their yield based on risk/reward preference
### Two Product Offerings
#### AZND (Asia Dollar)
* Credit backed USD yield token designed for capital stability
* Senior risk tranche, overcollateralized by the muBOND junior tranche (\~118% at inception)
* 80-90% of the yield from the Asset Pool is allocated to the AZND locking contract (see [locking](/protocol-overview/asia-dollar-aznd/locking))
#### muBOND
* Credit backed USD yield token designed for higher potential returns
* First loss credit tranche; returns get paid after AZND returns have been achieved
* Designed to absorb losses first in exchange for excess spread
* Reprices periodically to reflect performance of underlying portfolio
* 10-20% of the yield from the Asset Pool is allocated to muBOND holders
### Underlying Asset Pool
The underlying portfolio consists of high quality fixed income assets held with reputable TradFi custodians. These assets are all denominated in USD (no FX risk) and are principal protected at maturity
Principal protection comes in the form of contractual agreements of the asset borrowers to pay back principal and all stipulated interest payments at the end of the duration of a credit agreement. Principal protection is not a guarantee of no loss. It is the structural prioritization of repayment and recovery in the event of default
These assets include, but are not limited to:
* Government bonds
* Corporate bonds
* Bank bonds
* High Yield bonds
* Private Credit
We target a gross APY of 7-10% for the Asset Pool, although returns may deviate from these targets subject to markets and the performance of the underlying portfolio
# Asia Dollar ("AZND")
Asia Dollar (“AZND”) is a credit-backed USD yield token supported by high quality Asia government and corporate borrowers. AZND is designed for stability and steady yield. AZND is suitable for users seeking predictable returns while retaining full DeFi composability
* **Risk**: Senior (protected from losses by first-loss credit tranche)
* **Yield Allocation**: 80-90% of net yield from the Asset Pool
* **Collateral**: Portfolio of Asia credit assets, including public bonds and private credit; same portfolio underlies AZND and muBOND
* **Utility**: Freely transferrable onchain, usable in DeFi markets. Stake to earn yield
# Mint / Redeem
Direct minting and redemption of AZND is available to approved counterparties that have cleared Mu Digital's KYC procedures. Interested parties can reach out to us [here](https://037p3p59sth.typeform.com/to/eIuXBgF5)
AZND is also available for permissionless swaps onchain through our decentralized exchange (“DEX”) partners
### Minting
* Users can mint AZND using preferred stablecoins (such as USDC, USDT, or AUSD) on a 1-1 basis
* Minting can be processed almost instantaneously and sent to the user's wallet upon transfer of the relevant stablecoins
* There is no fee for minting
### Redemption
* Redemption requests by default enter a redemption queue
* Our licensed Singapore based fund partner relies on a weekly liquidity schedule, with redemptions processed by Tuesday for settlement the following week. In practice, expect \~7 calendar days between redemption and receipt of funds
* Amounts below a certain threshold may be processed immediately subject to availability in our onchain liquidity buffer. We intend to scale this threshold over time alongside our TVL
* There is no fee for redemption
# Locking
To earn the AZND share of yield from the underlying Asset Pool, AZND must be locked into the loAZND vault on supported blockchains. Unlocking AZND from the loAZND vault involves a 1-day cooldown period before withdrawal
### Locking Mechanics
* Users who lock AZND into the vault will receive loAZND in return. loAZND is a receipt token that follows the ERC-4626 standard for vault tokens
* loAZND is a liquid token and can also be used in DeFi protocols like any other yield-bearing vault token
* loAZND locked in the loAZND contract remain there and are not lent out / rehypothecated for any other purposes
* Yield is paid out in additional loAZND tokens deposited into the vault that tracks the share of yield allocated to AZND holders
* Yield is accumulated on a weekly basis and distributed evenly throughout the following week. This is done to even out the distribution of rewards and avoid gaming the reward system if rewards were distributed in one lumpsum
* Unlocking is subject to a 1-day cooldown period, the initial AZND tokens and additional AZND rewards are available for withdrawal at the end of the cooldown
# muBOND
muBOND is a credit-backed USD yield token supported by high quality Asia government and corporate borrowers. muBOND is designed for higher potential returns in exchange for providing insurance to AZND holders. muBOND is suitable for users seeking leveraged returns on the underlying Asset Pool while retaining full DeFi composability
* **Risk:** First loss credit tranche
* **Yield Allocation:** 10-20% of net yield from the Asset Pool; price adjusts periodically to reflect accrued yield
* **Collateral:** Portfolio of Asia credit assets, including public bonds and private credit; same portfolio underlies AZND and muBOND
* **Utility:** Freely transferrable onchain, usable in DeFi markets
muBOND repricing happens on a regular basis, to reflect mark to market changes in the underlying portfolio as well as accrual of yield. These price updates are expected to be published weekly at inception with the frequency intended to increase over time
# Mint / Redeem
Direct minting and redemption of muBOND is available to approved counterparties that have cleared Mu Digital's KYC procedures. Interested parties can reach out to us [here](https://037p3p59sth.typeform.com/to/eIuXBgF5)
muBOND is also available for permissionless swaps onchain through our DEX partners
### Minting
* Users can mint muBOND using preferred stablecoins (such as USDC, USDT, or AUSD) at the most recent published NAV
* Minting can be processed almost instantaneously and sent to the user's wallet upon transfer of the relevant stablecoins
* There is no fee for minting
### Redemption
* Redemption requests by default enter a redemption queue
* Our fund partner relies on a weekly liquidity schedule, with redemptions processed by Tuesday for settlement the following week. In practice, expect \~7 calendar days between redemption and receipt of funds
* Amounts below a certain threshold may be processed immediately subject to availability in our onchain liquidity buffer. We intend to scale this threshold over time alongside our TVL
* There is no fee for redemption
# How we Generate Yield
Mu Digital aims to deliver sustainable, predictable yield by allocating the portfolio into a diversified mix of USD-denominated, principal-protected real-world assets (RWAs) from the Asia Pacific region.
To achieve this, we have partnered with a Singapore regulated fund manager, Golden Hill Asset Management (“GHAM”), to manage the underlying portfolio. The team at GHAM is comprised of seasoned investment professionals that have previously managed multi-billion dollar portfolios at funds and global bulge bracket investment banks. This expertise helps Mu Digital strike the right balance of risk and yield to support our flagship products
### Asset Classes
The fixed income instruments that back the underlying Asset Pool will primarily comprise a mix of:
* **Government Bonds:** sovereign debt from creditworthy jurisdictions with a minimum rating of BBB
* **Corporate Bonds:** investment grade debt issued by established Asian companies with minimum ratings of BBB-
* **Bank Bonds:** debt issued by regulated financial institutions from Asia Pacific, including Globally Systemically Important Banks (G-SIBs). We will take positions across both senior and subordinated debt, subject to an average minimum issuer rating of BBB
* **High Yield Bonds:** speculative grade debt issued by large industrial corporations in Asia-Pacific with a minimum rating of BB
* **Private Credit:** direct lending and credit facilities to vetted borrowers, typically co-lending with other large financial institutions to manage counterparty risk
### Risk Management Framework
Mu Digital takes Risk Management very seriously and we have drafted a comprehensive [Risk Framework](/mechanics/risk-management-framework) with GHAM that is aligned with industry best practices to safeguard user funds while achieving healthy yields
# Risk Management Framework
We aim to deliver consistent, risk-adjusted returns by tracking and managing liquidity risk, credit risk, and price risk across the underlying Asset Pool
### Liquidity Risk
* Maintain minimum 80% allocation to liquid, freely tradable bonds (ie. capping illiquid private credit positions to 20% of the Asset Pool)
* Significant portion allocated to Investment Grade bonds that exhibit lower volatility
* Credit lines available with our prime broker to have access to fast liquidity while managing the selldown of the underlying bonds
### Credit Risk
* Target blended portfolio rating of BBB or higher
* Ongoing monitoring of credit events of all positions, with periodic assessment of the ratings drift of the overall portfolio
* Restrict Private Credit deals to co-investments with other reputable lenders to mitigate counterparty risk
### Price Risk
* Manage duration to average of 5, limiting adverse mark to market impacts of changes in rates
* Maintain maturity ladders and staggered bond durations to ensure regular cash flows without forced selling
* Active management strategy to take profit during times of portfolio outperformance
# Transparency and Reporting
Transparency is a core principle at Mu Digital and we intend to provide regular, verifiable updates on the underlying Asset Pool and our onchain treasury balances to give users clear visibility into the protocol's health and performance
### Onchain NAV Accounting
* Partnered with Pennyworks to provide NAV accounting for the reserves of the Asset Pool
### Protocol-Owned Wallets
* In addition to the proposed Insurance Fund, we also intend to hold some liquidity in onchain Treasury Wallets to help facilitate timely minting and redemption for approved users
* The addresses and balances of these wallets will be made available for users to verify holdings onchain in real time
* These wallets will be segregated from the Company's operational funds and kept completely distinct and separate
# Price Stability Mechanism
The protocol uses a risk tranching structure to maintain the price stability of AZND. This is achieved through the muBOND first loss credit tranche and the establishment of an Insurance Fund that we intend to fund with protocol fees over time
### **Loss Absorption via muBOND**
* **First Loss Credit Tranche:** muBOND represents \~15% of total protocol TVL and is the first-loss capital in the system
* **Mark-to-Market Protection:** if the underlying RWA Asset Pool experiences temporary price declines (e.g., from interest rate movements or credit spread widening), these losses are reflected in the NAV of muBOND, not AZND
* **Preserving AZND Value:** AZND, as the senior tranche, retains its principal value unless portfolio losses exceed the entire muBOND capital layer
* **Example:**
* Portfolio declines by 5% due to market movements
* Losses are absorbed entirely by muBOND NAV before AZND is impacted
### **Insurance Fund**
* **Purpose:** acts as an additional capital buffer to cover potential shortfalls that exceed muBOND’s junior capital
* Built over time using a portion of protocol fees
* **Deployment:** may be used to offset redemption shortfalls, support liquidity during stress events, or stabilize NAV during extreme volatility
# Fees
The protocol earns fees through two primary means:
* **Fees on minting and redemption**: currently set at zero; any future change will be communicated on official channels
* **Performance fees** (share of yield generated by the protocol):
* Mu Digital applies a performance-based fee designed to align the protocol’s incentives with users
* The protocol earns fees only when users earn yield. A 10% performance fee is applied to realized net yield generated by Mu Digital strategies
* For example, if a strategy generates 10% net annual yield, Mu Digital retains 1%, and users receive 9%
* There are **no management fees and no fees on principal**
Fees earned by the protocol will be used to deliver value to stakeholders and users including, but not limited to:
* **Insurance Fund:** build up a liquidity buffer to further support the protocol
* **Ecosystem Growth:** support integrations, partnerships, and other ecosystem initiatives
* **Token Buybacks:** strategic buybacks in the future, post any potential Token Generation Event (“TGE”)

# Smart Contract Architecture
Mu Digital’s smart contract architecture is designed for modularity, security, and seamless DeFi composability. It is organized into three primary contract categories:
* [**ERC-20 Contracts**](/technical-reference/smart-contract-architecture/erc-20-contracts)\
Define the core tokens of the Mu Digital ecosystem, including **AZND** and **muBOND**.\
Handle token standards, mint/redeem logic, and role-based permissions.
* [**loAZND Vault Contracts**](/technical-reference/smart-contract-architecture/staking-contracts)\
Manage AZND deposits and issue **loAZND**, a yield-bearing token that accrues value through repricing.\
Oversee reward accrual, cooldowns, lockup mechanics, and emissions distribution.
* [**Protocol Contracts**](/technical-reference/smart-contract-architecture/protocol-contracts)\
Coordinate core system logic, including the **PrimaryMarket** (KYC-gated access), **PriceFeed**, **Access Manager**, and **Timelock Controller**.
### **Mu Core**
Mu Protocol merges real-world asset stability with DeFi-native efficiency, delivering predictable yield through transparent, composable products.
* **Real-World Asset Backing** – Each product is fully collateralized by verifiable, income-generating assets, with all positions transparently recorded and auditable on-chain.
* **Repricing-Based Yield** – Yield accrues through controlled price adjustments rather than rebasing, preserving ERC-20 and ERC-4626 compatibility and enabling seamless integration across DeFi.
* **Flexible, Integration-Ready Architecture** – Designed for interoperability with major DEXs, lending markets, and yield platforms, while supporting multiple product configurations such as instant-liquidity pools, fixed-term vaults, and diversified yield strategies.
* **Data Transparency** – All collateral details, performance metrics, and yield history are accessible in real time through on-chain data and public dashboards.
# ERC-20 Contracts
Mu Digital’s token suite is built around ERC-20 standards, ensuring broad compatibility with the DeFi ecosystem while maintaining clear roles for each asset.
#### **Overview**
| **Token** | **Type** | **Purpose** | **Standard** |
| ---------- | ------------ | ------------------------------------------------------------------------------------------------------------------------------ | ------------ |
| **AZND** | Stable Asset | Marked 1:1 to USDC/USDT, non-yield bearing. Mint/redeem restricted to KYC-verified users via PrimaryMarket. | ERC-20 |
| **loAZND** | Yield Token | Minted by depositing AZND into an ERC-4626 vault, accrues yield via repricing. | ERC-4626 |
| **muBOND** | Yield Token | Collateralized by an underlying pool of real-world assets; yield is reflected through price appreciation rather than rebasing. | ERC-20 |
#### **Key Mechanics**
* **Core Functions** – `mint`, `redeem`, `transfer`, `approve`, plus role-gated administrative functions.
* **Access Control** – Role-based permissions for Minter, Burner, and Admin functions, with timelocked execution for critical changes.
* **Standards Compliance** – ERC-20 for token logic, ERC-4626 for vault mechanics, and selected EIP extensions for enhanced interoperability.
* **Security & Upgradeability** – Audited contracts with defined upgrade paths, pausable operations, and restricted role assignments to protect protocol integrity.
# Staking Contracts
### **loAZND Vault**
The loAZND Vault enables users to deposit AZND and receive loAZND, a yield-bearing token representing a share of the vault’s underlying real-world asset (RWA) strategies. Yield is generated off-chain and reflected in loAZND’s value through periodic repricing.
#### **Overview**
| **Parameter** | **Description** |
| ----------------- | -------------------------------------- |
| **Standard** | ERC-4626 vault |
| **Deposit Asset** | AZND |
| **Receipt Token** | loAZND |
| **Reward Source** | Yield from underlying RWA pool |
| **Redemption** | AZND share value after cooldown period |
#### **Key Mechanics**
* **Deposit & Mint** – Users deposit AZND to mint loAZND, which represents their proportional ownership in the vault.
* **Yield Accrual** – Vault yield is distributed via price repricing, increasing loAZND’s redeemable value over time.
* **Cooldown Period** – Withdrawals are subject to a protocol-defined cooldown before redemption.
* **Redemption** – Upon cooldown expiry, loAZND is burned and AZND is returned at the updated price.
* **Admin Controls** – Role-gated functions for updating vault parameters, reward rates, and integration settings.
* **Security** – Built with audited contracts, upgradeable architecture, and timelocked admin actions to ensure protocol safety.
# Protocol Contracts
Protocol contracts contain the core system logic for Mu Digital.
#### **PrimaryMarket**
